GEORGE D. SMITH, OF PATERSON, N EW JERSEY.

RAILWAY-FROG.

SPECIFICATION forming part of Letters Patent No. 790,663, dated May 23, 1905.

Application filed February?, 1905. Serial No. 2441.525. I

To all whom t may concern:

Be it known that I, GEORGE D. SMrrH,a citizen of the United States, residing in Paterson, Passaic county, New Jersey, have invented certain new and useful Improvements in Railway-Frogs; and vI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to reference marked thereon, which form a part of this specification.

My invention relates to railway-frogs, and it has reference particularly to that type of frog wherein the wings are pieces (rails) sep'- arate from each other and bent to have the residered useless and had tobe entirely removed and replaced by a new one. 'This means a considerable expense, especially where the frog is one which is in frequent use.

By my invention the life of the frogis doubled and the expense of equipment in the matter of frogs cut down in proportion.

My invention will be found fully illustrated in the accompanying drawings, wherein-`- Figure l shows it as applied to a plain frog. Fig. 2 shows it as applied to what is commonly known as a spring-rail frog. Fig. 3 is a transverse sectional view on the line fr in Fig. l; and Fig. 4: is a view like Fig. 3, showing a means for compensating for the wear on the point of the frog.

In the ordinary frog of the kind in view the rails forming the wings are made sufficiently long and bent at such an angle at one end that they will match with the adjacent rails; but at the other end they are bent off with regard only to securing enough clearance between themselves and the point of the frog so that the wheel-flanges will not ride up onto them, usually in a curve. My invention contemplates making both end portions of the wings alikethat is to say, bending them both at an angleand to the same degree and preferably giving both the same length from the angles to the extremity. Then when the wings wear at the points above referred to-namely,

just beyond the tip of the point and where e denotes the ends ofthe wings, which are.

shaped (as at present) to match with the rails CZ, and f theends, shaped in accordance with my invention to conform to the ends e, so that they will match the railscZ upon removing the wings, reversing them end for end, and interchanging their positions.

Since the point yof the frog also wears, I contemplate placing this in the same renewed condition as the wings after reversal bydriving a wedge g under the point, (see Fig. 4,) thereby raising its top surface to the level of the top surfaces of the wings.

Having thus fully ldescribed my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. A railway-frog having its wings separate from each other, the end portions of each wing being bent off at angles at the same degree and being of the same length from the angles tojtheir extremities, substantially as described.

2. A railway-frog having separable wings formed end for end alike, in combination with means for elevating the point of the frog,-sub stantially as described. y

- 'In testimony that I claim the foregoing I have hereunto set my hand this 3d day of February, 1905.
